Description

  The present invention relates to a scenario generation device, a scenario generation method, and a scenario generation program for creating a test scenario used in a test device for testing a mobile communication terminal.

  In developing mobile communication terminals such as mobile phones and mobile devices, a test device that simulates a base station is used to test whether the mobile communication terminal under development can communicate normally with the base station according to the communication standard. It is done. In such a test apparatus, a test scenario created in advance is stored. The test scenario describes an operation sequence of the test apparatus and a communication sequence with the mobile communication terminal. In a communication test of a mobile communication terminal, the test apparatus is operated as a pseudo base station according to this test scenario and communicated with the mobile communication terminal to be tested to check whether normal communication is performed. Is called. For this reason, development of a scenario generation device for creating a test scenario is also an important issue.

  By the way, in the mobile communication standard, broadcast information is defined as important information transmitted from the base station to the mobile communication terminal. The broadcast information includes, for example, base station location information, neighboring cell information, information for performing transmission restriction control, and the like, and broadcast transmission to mobile communication terminals is performed every 128 frames cyclically. Is done.

  For example, in W-CDMA (Wideband Code Division Multiple Access) communication scheme, broadcast information is composed of one MIB (Master Information Block) and a plurality of SIBs (System Information Block).

  The MIB includes information for informing the mobile communication terminal of the SIB configuration (transmission schedule of which SIB is transmitted at which frame) and broadcast information of the SIB that is broadcast simultaneously in units of 128 frames. Contains information for notifying the change.

  There are various types of SIBs such as SIB1, SIB2, SIB3,. For example, SIB1 broadcasts common information in units of cells, and SIB2 and subsequent SIBs broadcast common information in units of cells.

  The broadcast information can optionally include a plurality of SBs (Scheduling Blocks). The SB contains SIB scheduling information (transmission schedule information).

  In W-CDMA, when transmitting these MIB, SIB, and SB blocks, the base station allocates and transmits one block every other frame in a repetition of 128 frames. These blocks are classified according to communication standards into those in which the allocation position and the number of allocations in 128 frames are fixed as in MIB and those in which the allocation position and the number of times can be arbitrarily set.

  Of course, the communication sequence related to the transmission of the broadcast information is also included in the test scenario described above, and at the time of the test execution, each mobile communication terminal to be tested from the pseudo base station based on the set transmission schedule. Blocks are sent cyclically.

  The broadcast information schedule generation means displays the second transmission schedule setting environment simultaneously with the first transmission schedule setting environment, and reflects the input to one transmission schedule setting environment to the other transmission schedule setting environment. It is good also as what makes it.

  Thereby, when the scenario creator confirms the setting contents of the transmission schedule, the confirmation accuracy can be expected to be improved by confirming the setting contents of the two transmission schedule setting environments.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a functional configuration of a scenario generation apparatus according to an embodiment of the present invention.

  The scenario generation device 1 includes a scenario generation unit 10, an operation unit 20, a display control unit 30, and a display unit 40.

  The scenario generation unit 10 generates a test scenario 50 used in a test apparatus that tests the operation of the mobile communication terminal while operating as a pseudo base station of the mobile communication terminal, and includes a CPU (Central Processing Unit), It consists of computer hardware elements including main memory, input / output interface, etc., and software elements that are scenarios generation programs.

  The scenario generation unit 10 includes a message generation unit 11, a control sequence generation unit 12, and a scenario generation unit 13 as functional elements.

  The message generator 11 is a unit that generates various messages distributed from the test apparatus to the mobile communication terminal. One of the messages distributed from the test apparatus to the mobile communication terminal is broadcast information. The message generator 11 includes a broadcast information schedule generator 111 that sets the broadcast information transmission schedule and the content of broadcast information for each type, and a broadcast information content setting unit 112 that sets the content of broadcast information. The broadcast information content setting unit 112 includes an MIB automatic generation unit 113 that automatically sets the MIB content based on the SIB transmission schedule set by the broadcast information schedule generation unit 111.

  In this message generation unit 11, the broadcast information schedule generation unit 111 is more specifically a table used to support generation of a broadcast schedule of broadcast information by a test scenario creator (hereinafter referred to as “scenario creator”). By outputting the information of the transmission schedule setting environment in the format to the display control unit 30, the transmission schedule setting environment in the table format is displayed on the display unit 40. The broadcast information schedule generation unit 111 then transmits a broadcast schedule of broadcast information based on information input by the scenario creator using the operation unit 20 with respect to the transmission schedule setting environment in a tabular format displayed on the display unit 40. Is generated.

  In more detail, the notification information content setting unit 112 supplies the display control unit 30 with information on the content setting environment used to support the setting of the content of the notification information by the scenario creator. The content setting environment of the broadcast information is displayed. The notification information content setting unit 112 sets the content of the notification information based on the information input by the scenario creator using the operation unit 20 for the content setting environment displayed on the display unit 40.

  The control sequence generation unit 12 is a unit that generates a control sequence that is a procedure for the test apparatus to perform communication with the mobile communication terminal.

  The scenario generation unit 13 generates the notification information based on the various messages including the transmission schedule of the notification information and the content of the notification information generated by the message generation unit 11 and the control sequence generated by the control sequence generation unit 12. This is a unit for generating a test scenario 50 consisting of a description in a predetermined script language concerning a communication sequence.

  Further, in the configuration other than the scenario generation unit 10 in the scenario generation device 1, the display control unit 30 displays the display unit 40 from the information of the transmission schedule setting environment and the content setting environment in a tabular format output from the notification information schedule generation unit 111. Generate data for display in. The display unit 40 has a display screen, and visualizes the display data supplied from the display control unit 30 on the screen. The operation unit 20 is input means such as a mouse and a keyboard that can be operated by the user.

  The scenario generation program is stored, for example, in a storage device such as a hard disk drive (not shown), and is loaded into the main memory using the operation unit 20 in accordance with an activation instruction given by the user. The scenario generation program loaded in the main memory is read and executed by the CPU. That is, the scenario generation program can be installed as an application program in a computer such as a personal computer, for example. In order to enable introduction into a computer, a scenario generation program can be recorded and distributed on a storage medium such as a DVD (Digital Versatile Disk) or a Blu-ray Disc (registered trademark). Alternatively, it can be distributed by downloading from a server device via the Internet.

(Operation of scenario generation device 1)
In this scenario generation device 1, a notification information schedule generation unit 111 generates a notification information transmission schedule. This process is performed based on an operation input from the operation unit 20 by the scenario creator, and a transmission schedule setting environment (hereinafter referred to as “first transmission schedule setting”) in a tabular format presented on the display unit 40 by the notification information schedule generation unit 111. Called "environment").

  When generating the notification information transmission schedule using the first transmission schedule setting environment in the tabular format, the scenario creator can operate the operation unit 20 to generate the notification information transmission schedule. A specific configuration of the first transmission schedule setting environment and a specific generation method of the transmission schedule using the first transmission schedule setting environment will be described later.

  When the first transmission schedule setting environment is displayed on the display unit 40, the scenario creator operates the operation unit 20 to select the notification information whose contents are to be set, and the content setting environment for the selected notification information. An instruction to call can be entered. In response to this instruction, the broadcast information content setting unit 112 causes the display unit 40 to display a content setting environment for the selected broadcast information. When the scenario creator operates the operation unit 20 and inputs various parameters to the content setting environment, the broadcast information content setting unit 112 accepts these parameters as the set content of the broadcast information.

  The broadcast information setting content includes, for example, an area range, a UE (user equipment) mode / state in which the block is valid, a UE mode / state in which the block is read, scheduling information (SIB position and repetition interval, etc.), system, etc. It includes information correction.

  After the generation of the broadcast schedule of the broadcast information, the setting of the content of the broadcast information, and the generation of the communication sequence by the control sequence generator 12 are completed as described above, the scenario creator operates the operation section 20 to operate the test scenario. 50 generation instructions can be input. Upon receiving the test scenario 50 generation instruction, the scenario generation unit 13 generates the test scenario 50 based on the transmission schedule of the notification information, the content of the notification information, and the communication sequence.

(Description of first transmission schedule setting environment)
Next, an outline of the first transmission schedule setting environment will be described.

In the first transmission schedule setting environment of the present embodiment, the frame number field indicating the frame number indicating the position of a frame that can be allocated for transmission of broadcast information and the setting of the broadcast information type name are accepted from the scenario creator. One type of information setting field is composed of the type name setting field that can be used.
For example, in W-CDMA, the broadcast information is broadcast simultaneously in units of 128 frames, and one block is allocated and transmitted every other frame, so the number of information setting fields is 64.

  If all the 64 information setting fields are displayed in one row or column, it is difficult to refer to all the information setting fields without scrolling due to screen size restrictions. Therefore, in this embodiment, the information setting fields are arranged in a matrix so that the entire table can easily fit on the screen, and the listing efficiency is improved, thereby improving the setting efficiency of the transmission schedule.

  In the W-CDMA communication standard, the MIB is assigned to the first frame of 128 frames (frame number = 0) and transmitted, and thereafter the MIB is transmitted once every eight frames. In the present embodiment, the tabular configuration (the number of rows and the number of columns) of the first transmission schedule setting environment is optimized in consideration of the transmission periodicity of the MIB.

  That is, in the table format of the first transmission schedule setting environment, the number of information setting fields for one row (or one column) arranged in the order of the frame number is set to the direction of the row, and the number of information setting fields is set to the MIB transmission. The number of frames as a period is n, and is a multiple of n / 2. For example, since the number of frames, which is the MIB transmission cycle, is 8, a multiple of 4 is set as the number of information setting fields for one row (or one column). As a result, each information setting column in which the MIB should be set according to the communication protocol is arranged in a specific column (or row) of the table, improving the listability and improving the transmission schedule setting efficiency.

Next, a specific example of the first transmission schedule setting environment will be described.
FIG. 2 is a diagram illustrating an initial state of the first transmission schedule setting environment.

  In this specific example, one information setting field 100 includes a frame number field 110 that is a display field for a frame number (Frame No.) and a type name setting field 120 that is a setting field for a type name (Block Type) of broadcast information. Composed. This information setting field 100 is a matrix element. The number of information setting columns 100 for one row (number of columns) is 8, and the number of information setting columns 100 for one column (number of rows) is 8. In this table format, the ascending order of the frame numbers is matched to the direction of the rows. That is, the frame number = 0 is assigned to the leftmost information setting column 100 of the top row of this matrix, and the remaining seven information setting columns 100 of the row are sequentially assigned the frame number = 2, 4 from the left. , 6, 8, 10, 12, and 14 are assigned. Similarly, the frame number = 16, 18, 20, 22, 24, 26, 28, 30 is assigned to the information setting column 100 in the next row in order from the leftmost one, and the same applies to the subsequent rows. Is assigned a frame number. Then, frame number = 126 is assigned to the information setting column 100 at the right end of the bottom row.

  In the initial state shown in FIG. 2, the type name setting column 120 of all the information setting columns 100 is blank so that the scenario creator can recognize at a glance that the setting of the type name has not been completed. Alternatively, a mark indicating that it is not set may be displayed.

  Next, an operation method of the first transmission schedule setting environment will be described.

  In the operation of the first transmission schedule setting environment, basically, the scenario creator selects the information setting column 100 for which the type name of the broadcast information is to be set by operating the operation unit 20, and the selected information setting column is selected. The procedure is such that a type name is input to the type name setting field 120 of 100 by operating the operation unit 20 and this is repeated.

Here, the following types are prepared as a method for inputting the type name in the type name setting field 120.
Method 1. A method of directly inputting a text code of a type name using a keyboard or the like as the operation unit 20.
Method 2. A method of inputting a category name using a pull-down menu for each category name setting field 120.
Method 3. A method of entering type names together using a pull-down menu in units of columns.

  A method of inputting the type name using the pull-down menu of method 2 and method 3 will be described.

(Details of Method 2)
First, the scenario creator uses the mouse or keyboard that is the operation unit 20 to select the information setting column 100 for the frame number for which the type name of the notification information is to be set. More specifically, the type name setting field 120 of the information setting field 100 is selected by a click operation or the like. The notification information schedule generation unit 111 receives the information generated by this selection operation, and displays a pull-down menu for selecting the type of notification information along with the type name setting field 120.

FIG. 3 is a diagram showing an example of a pull-down menu 130 for selecting the type of notification information.
The pull-down menu 130 displays a list of notification information type names. In the pull-down menu, it is desirable that the type names of the notification information are displayed in order from the top in a hierarchical order. For example, it is desirable to display MIB, SB1, SB2, SIB1, SIB2,.

  In this pull-down menu 130, the scenario creator can select an arbitrary type name by operating the operation unit 20. The notification information schedule generation unit 111 receives the information generated by this selection operation, stores the selected type name in the main memory in association with the frame number, and stores it in the type name setting field 120 of the information setting field 100. The type name is displayed.

  The function of selecting a category name by using the pull-down menu 130 is similarly employed in the category name setting column 120 of all the information setting columns 100 in the first transmission schedule setting environment. Accordingly, the scenario creator completes the generation of the broadcast schedule of the broadcast information by repeating the selection operation of the type name by the pull-down menu 130 for each information setting field 100 in the first transmission schedule setting environment. Can be made.

  As described above, the method of inputting the type name by using the pull-down menu 130 for each type name setting field 120 of method 2 is a reliable method in which the type name can be input for each frame number.

(Details of Method 3)
Next, a method of inputting the category names collectively using the pull-down menu 130 in units of columns in Method 3 will be described.

Method 3 is a method that focuses on efficiency.
As already described, in the table format of the first transmission schedule setting environment according to the present embodiment, the number of information setting fields 100 for one line arranged in the order of frame numbers is set to the MIB direction by aligning the ascending order of the frame numbers with the direction of the lines. By setting the number of frames that is the transmission cycle of n as a multiple of n / 2, each information setting column 100 in which the MIB is to be set is arranged in a specific column of the table. Also, among other types of blocks, there are those in which the frame position where the block is transmitted is determined based on the frame position where the MIB is transmitted, and each information setting column 100 where such type should be set. May also be aligned to specific columns of the table. Method 3 is a method suitable for setting the same type name in units of columns as described above.

  First, the scenario creator uses the mouse or keyboard that is the operation unit 20 to select all the information setting fields 100 belonging to the column for which the type name of the notification information is to be set. The notification information schedule generation unit 111 receives information generated by this selection operation, and displays a pull-down menu for selecting the type of notification information along with the selected column.

FIG. 4 is a diagram showing a display example of a pull-down menu 140 that can select the type of broadcast information in units of this column.
The configuration of the pull-down menu 140 itself may be the same as the pull-down menu 130 for each type name setting field 120 shown in FIG.

  In this pull-down menu 140, the scenario creator can select an arbitrary type name by operating the operation unit 20. The broadcast information schedule generation unit 111 receives the information generated by this selection operation, stores the selected type name in the main memory in association with each frame number belonging to the column, and belongs to the column The type names are displayed in the type name setting fields 120 of the plurality of information setting fields 100, respectively. FIG. 5 shows an example of a first transmission schedule setting environment in which the setting of the type name in the type name setting field 120 of the plurality of information setting fields 100 in units of columns is completed. FIG. 5 illustrates a case where “MIB” is set as the type name in the type name setting column 120 of the plurality of information setting columns 100 belonging to the leftmost column.

The method for inputting the type name in the type name setting column 120 of the information setting column 100 has been described above. However, the type name once input can be changed at any time by the direct input method according to the method 1, for example.
Therefore, after the type name is set in units of columns by the method 2, the type name in the type name setting column 120 of some of the information setting columns 100 is changed by the direct input method according to the method 1. Can also be done.

  Note that the target unit for which the type name can be input using the pull-down menus 130 and 140 is not only the unit of the information setting column 100 and the unit of the column, but also the unit of a plurality of information setting columns 100 continuous in the column direction. There may be.

  FIG. 6 shows an example of a first transmission schedule setting environment in which the setting of the broadcast information type name for all frame positions, that is, the setting of the transmission schedule, is completed by selectively using the above method 1-3.

  In this example, “MIB” is set as the type name in the type name setting column 120 of each information setting column 100 belonging to the first column and the fifth column from the left of each row. As described above, when setting the MIB type name in which the transmission frame allocation position is periodically fixed according to the communication standard, it is possible to set in a batch unit and to set the transmission frame Similarly, the types whose allocation position is determined based on the transmission position of the MIB can be set collectively in units of columns, so that the overall setting efficiency can be greatly improved. For example, in the example of FIG. 6, SB1 is set in the second column from the left end.

The scenario creator may display the information setting column 100 of a specific type in a different color for each type so that the difference between the types can be easily visually recognized when checking the generated transmission schedule.
FIG. 7 shows a case where, for example, at least one of the background color and characters in the information setting column 100 of “MIB”, “SB1”, “SIB11”, and “SIB19” as type names is displayed in the same color for each type. It is an example. The scenario creator may arbitrarily set which color is assigned to which type name. At this time, it is not always necessary to assign colors to all types.

(About the MIB automatic generation unit 113)
Next, details of the MIB automatic generation unit 113 will be described.
The MIB automatic generation unit 113 automatically sets the contents of the MIB based on the SIB transmission schedule set by the broadcast information schedule generation unit 111.

Next, the MIB automatic generation operation by the MIB automatic generation unit 113 will be described.
The MIB is composed of schedule information indicating to which frame one or more SIBs transmitted in subsequent frames are allocated and transmitted. Specifically, the MIB indicates the SIB transmission cycle (SIB # REP) and the SIB transmission of the SIB in the period defined by the value of the transmission cycle (SIB # REP). Contains information on allocation position (SIB # POS). Therefore, if all the SIB frame positions from the frame position at which the MIB is transmitted to the frame position at which the next MIB is transmitted are set, the contents of the MIB are also determined by itself.

  That is, as described above, the MIB automatic generation unit 113 sets one or more SIB schedule information (frame numbers) set between the frame position at which the MIB is transmitted and the frame position at which the next MIB is transmitted. Obtained from the notification information schedule generation unit 111. The MIB automatic generation unit 113 automatically generates the contents of the MIB based on the acquired schedule information (frame number) of one or more SIBs. If the MIB contents have been completed by input from the scenario creator before setting the SIB schedule information (frame number), the MIB automatic generation unit 113 automatically generates the MIB contents. Is compared with the input content, and a warning is issued if there is a mismatch. This warning is made in a way that the scenario creator can perceive. For example, there is a method of performing display in the first transmission schedule setting environment and the content setting environment.

  This MIB automatic generation can improve the setting efficiency and setting accuracy of MIB contents.

(Modification 1)
In the first modification, in addition to the first transmission schedule setting environment, a new transmission in which a transmission schedule of broadcast information can be set by inputting a transmission cycle, the number of divided blocks, an allocation position, and the like for each type of broadcast information. The schedule setting environment is introduced as the second transmission schedule setting environment. The second transmission schedule setting environment can be displayed on the display unit 40 simultaneously with the first transmission schedule setting environment or by switching between the two.

FIG. 8 is a diagram showing a specific example of the second transmission schedule setting environment.
As shown in the figure, the second transmission schedule setting environment includes a broadcast information type name (Block Type) setting field 220, a transmission cycle (SIB # REP) setting field 230, and the number of divided blocks (SEG). The #COUNT) setting field 240 and the allocation position (SIB # POS) setting field 250 constitute a group of information setting fields 200.

The transmission cycle (SIB # REP) is a value indicating how many frame cycles the block of the type name set in the type name setting field 220 is transmitted.
The number of divided blocks (SEG # COUNT) is a value indicating how many blocks the content of the block of the type name set in the type name setting field 220 is divided and transmitted.
As for the allocation position (SIB # POS), the block of the type name set in the type name setting field 220 is transmitted as the block number in the cycle defined by the value of the transmission cycle (SIB # REP). It is a value indicating Note that the value of the allocation position (SIB # POS) is not the number of frames but the value of (number of frames / 2). This is because the broadcast information block is transmitted in a cycle of two frames.

In the specific example of the second transmission schedule setting environment illustrated in FIG. 8, for example, when focusing on the information setting field 200 whose type name is “MIB”,
Transmission cycle (SIB # REP) = 8
Number of divided blocks (SEG # COUNT) = 1
Allocation position (SIB # POS) = 0
It is.

  This represents the setting contents in which the MIB is transmitted in a cycle of 8 frames, the contents are transmitted in one frame without being divided, and transmitted as the first (0th) frame of the 8 frames.

Also, focusing on the information setting field 200 whose type name is “SIB5 / SIB5bis”,
Transmission cycle (SIB # REP) = 32
Number of divided blocks (SEG # COUNT) = 3
Allocation position (SIB # POS) = 5, 6, 7
It is.

  This is because broadcast information with a type name of “SIB5 / SIB5bis” is transmitted in a cycle of 32 frames, the contents of which are divided into three blocks and transmitted, and these three blocks are the first frame (number 0) of the 32 frames. ) From 6th, 7th, and 8th (5th, 6th, and 7th) frames.

  In this way, by introducing a second transmission schedule setting environment in which a transmission schedule of broadcast information can be set by inputting a transmission cycle, the number of divided blocks, an allocation position, and the like for each type of broadcast information, The transmission schedule can be set by a method different from the transmission schedule setting environment.

  Note that the setting column for the number of divided blocks in the second transmission schedule setting environment is not necessarily employed for the purpose of setting the block allocation position.

  Input of information to the first transmission schedule setting environment and the second transmission schedule setting environment is performed in synchronization with each other. That is, the broadcast information schedule generation unit 111 replaces information input to the first transmission schedule setting environment with equivalent information in the second transmission schedule setting environment, and inputs the information to the second transmission schedule setting environment at the same time. Similarly, the broadcast information schedule generation unit 111 replaces information input to the second transmission schedule setting environment with equivalent information in the first transmission schedule setting environment and inputs the information to the first transmission schedule setting environment at the same time. Thereby, when the scenario creator confirms the setting contents of the transmission schedule, the confirmation accuracy can be improved by confirming the setting contents of the two transmission schedule setting environments.

  Also in this second transmission schedule setting environment, for example, as shown in FIG. 9, the information setting column 200 of a specific type may be displayed in a distinguishable manner by displaying it in a different color for each type. In this case, it is preferable to unify the relationship between the type and the color between the two transmission schedule setting environments. Further, the above pull-down menu may be adopted for the input to the setting field 220 of the type name (Block Type) of the broadcast information.

  The broadcast information schedule generation unit 111 switches between the first transmission schedule setting environment and the second transmission schedule setting environment according to an instruction given from the scenario creator using the operation unit 20, and displays them. It is possible to display at the same time.

(Modification 2)
FIG. 10 is a diagram illustrating a modification of the first transmission schedule setting environment.
In the first transmission schedule setting environment having the matrix structure shown in FIG. 2, although one information setting column 100 is an element of the matrix, the information setting column 100 includes a frame number column 110 and a type name setting column 120. Since the frame number column 110 and the type name setting column 120 are arranged vertically, it is difficult to understand the boundary between lines. Therefore, in this modification, a space 102 is provided between the original lines having the information setting column 100 as an element of the matrix so that the boundary between the lines can be easily understood.

  In addition, in order to make the boundary between lines easy to understand, the type and color of a line separating lines may be different from the type and color of a line separating a frame number column and a type name column.

(Modification 3)
FIG. 11 is a diagram showing another modification of the first transmission schedule setting environment.
In another modification of the first transmission schedule setting environment, in the information setting column 100, the frame number column 110 and the type name setting column 120 are arranged side by side in the row direction. The number (number of rows) of information setting columns 100 for one column is “16”, and the number (number of columns) of information setting columns 100 for one row is “4”.

  In this modification of the first transmission schedule setting environment, the ascending order of the frame numbers is matched to the direction of the columns. That is, frame number = 0 is assigned to the information setting column 100 at the upper end of the leftmost column, and frame numbers = 2, 4, 6, 8, 10, 12, 14 are assigned to the remaining seven information setting columns 100 in the column, respectively. , 16, 18, 20, 22, 24, 26, 28, 30 are assigned in order. Similarly for the information setting column 100 in the next column, the frame numbers = 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56 in order from the top. , 58, and 60, and frame numbers are similarly assigned to the subsequent columns. Then, the frame number = 126 is assigned to the information setting column 100 at the lower end of the rightmost column.

  In addition, according to the modification of the first transmission schedule setting environment, since the column is configured in units of 32 frames, when setting according to the W-CDMA communication protocol, the first row from the top of each column, The contents of the type name setting field 120 of the information setting field 100 corresponding to each element of the 5th line, 9th line, and 13th line are aligned with “MIB”. Therefore, by displaying a menu similar to the pull-down menu 140 shown in FIG. 4 with each row selected, the category name is collectively displayed in units of rows by the category name selection operation by the scenario creator for this menu. Can be set. Further, in the example of FIG. 11, the notification information such as “SB1”, “SIB1”, “SIB3”, and “SIB5 / SIB5bis” is arranged side by side for each type. By the selection operation of the category name by the creator, it can be set in units of rows.

  In addition, since the frame number column 110 and the type name setting column 120 are arranged side by side in the information setting column 100, a space 102 is provided between the columns so as not to obscure the boundaries between the columns. Yes. Furthermore, also in this table format, color classification may be performed for each type of notification information.

(Modification 4)
The number of rows and the number of columns in the first transmission schedule setting environment may be fixed in the system in consideration of restrictions on the communication protocol, or may be designated by the scenario creator using the operation unit 20. You may make it changeable according to each value of a number and the number of columns.

[Additional notes]
In the above description, since the W-CDMA system is taken as an example, “frame” is used as the broadcast information transmission schedule unit. However, when the present invention is applied to the LTE system, for example, the “ The “frame” may be read as “subframe” which is a schedule unit of the LTE system.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
